Definitions
- the present invention relates to cursor control devices and, more particularly, to optical cursor control devices.
- a mouse is extensively adopted in a computer in order to control a position of a cursor viewed on a display device.
- This mouse may be classified into a ball mouse and an optical mouse.
- the ball mouse is placed on a surface of a medium and has a ball which contacts with the surface of the medium.
- a dust or the like is adhered to a surface of the ball and causes malfunction of the ball mouse.
- the optical mouse is widely used instead of the ball mouse.
- the optical mouse generally comprises a light emitting device for emitting light onto the surface of the medium and an optical sensor for sensing vertically reflected lights of the lights reflected from the surface of the medium.
- a device generating infrared rays or visual spectral rays is extensively used.
- the medium may be classified into two categories. One is a pad on which specific patterns are drawn, and the other is a typical worktable with irregular surface morphology. If the pad is adopted, there exists a constraint that the optical mouse should be used only on the pad. On the other hand, if the typical worktable is used instead of the pad, the light emitted from the light emitting device should have a great intensity of illumination higher than 1,600 lux. This is for maximizing the intensity of the vertically reflected lights, which are reflected from the surface of the worktable, to increase a margin of sensitivity of the optical sensor.
- the optical mouse is taught in U.S. Pat. No. 5,686,720 to Tullis, entitled “Method and Device for Achieving High Contrast Surface Illumination”.
- the optical mouse disclosed in the U.S. Pat. No. 5,686,720 is characterized in that an incident ray having an incident angle smaller than 160 is irradiated onto a surface of a medium having an irregular surface morphology.
- the incident angle means an angle between the incident ray and the surface of the medium.
- the infrared rays or visual spectral rays are used to sense the location of the optical mouse. Accordingly, eyes of an operator who manipulates the mouse may be damaged. Moreover, since the light emitted from the light emitting device is required to have an intensity of illumination higher than a specific value, power consumption of the optical mouse is remarkably higher than that of the ball mouse.
- the present invention provides an optical cursor control device comprising a worktable and an optical mouse moved on the worktable by an operator.
- the optical mouse includes a case; a light guide disposed at a sidewall of the case for guiding external light of the case into the case; an optical sensor disposed in the case for sensing the light outputted from the light guide; and a printed circuit board for processing a signal outputted from the optical sensor to generate an output signal corresponding to a position of the case.
- the light guide may be a prism or a light amplifying mean.
- the prism has a first area for transmitting light reflected from a surface of the worktable adjacent to the case, and a second area for illuminating the light, which is introduced through the first area, to the optical sensor.
- the optical mouse includes a lower panel with an opening. Accordingly, the light passing through the light amplifying mean is illuminated onto the surface of the worktable through the opening, and the light illuminated onto the surface of the worktable is reflected and illuminated to the optical sensor.
- the optical mouse may further include a light emitting device installed in the case.
- the light emitting device can be manually or automatically operated.
- the light emitting device is turned on when the external light has a weak intensity. Lights from the light emitting device are irradiated onto the surface of the worktable through the opening.
- the present invention comprises an optical cursor control device having a light concentrating pad and an optical mouse moved on the light concentrating pad by an operator.
- the light concentrating pad includes a light concentrating plate; an optical wave guide for passing light reflected from the light concentrating plate; a lower reflecting plate attached to a bottom of the optical wave guide for upwardly reflecting the light introduced through the optical wave guide; and an upper transparent plate attached to a top of the optical wave guide for passing the light reflected from the lower reflecting plate.
- the light concentrating pad includes a light source; an optical wave guide for passing light emitted from the light source; a lower reflecting plate attached to the bottom of the optical wave guide for upwardly reflecting the light introduced into the optical wave guide; and an upper transparent plate attached to the top of the optical wave guide for passing the light reflected from the lower reflecting plate.

- FIG. 3 a is a schematic perspective view of an optical cursor control device according to a third embodiment of the present invention.
- FIG. 3 b is a schematic cross-sectional view of the optical cursor control device shown in FIG. 3 a ;
- FIG. 4 is a cross-sectional view showing a pad of an optical cursor 0 . 20 control device according to a fourth embodiment of the present invention.
- FIG. 1 is a schematic cross-sectional view showing an optical cursor control device according to a first embodiment of the present invention.
- the optical cursor control device includes a worktable 110 , and an optical mouse 100 horizontally moved on the worktable 110 by an operator.
- the worktable 110 has an upper surface 110 a with irregular surface morphology.
- the optical mouse 100 includes a case 1 for providing a closed space, and a light guide 3 , e.g., prism mounted on a sidewall of the case 1 .
- a side of the prism 3 is outwardly protruded from the case 1 to receive light reflected from the upper surface of the worktable 110 adjacent to the case 1 .
- external light 19 of the case 1 is reflected by the upper surface 110 a adjacent to the case 1 to thereby pass through a lower surface of a protruded portion of the prism 3 , i.e., a first area.
- the light introduced into the prism 3 through the first area is illuminated into the case 1 through a second area of the prism 3 .
- the light passing through the prism 3 is illuminated to an optical sensor 7 , which is mounted inside the case 1 .
- first and second light concentrating means 3 a and 3 b are disposed in the first and second areas, respectively.
- the first and second light concentrating means 3 a and 3 b may be convex lenses.
- a sensing margin of the optical sensor 7 can be improved.
- the optical sensor 7 is mounted on a printed circuit board 5 , which is disposed inside the case 1 .
- an output signal of the optical sensor 7 is converted to an electric signal, which corresponds to a current position of the case 1 , by a predetermined circuit mounted on the printed circuit board 5 , and the converted signal is transferred to a main board of a computer via wiring 17 connected to the printed circuit board 5 .
- a switch module 9 is mounted on a predetermined area of the printed circuit board 5 .
- a horizontal support 11 is disposed above the switch module 9 .
- a hinge 13 which is fixed inside the case 1 , is connected to one side of the support 11 , while a button 15 , which penetrates the top of the case 1 , is positioned on the other side of the support 11 .
- the support 11 has a restoring force, provided by a resilient member (not shown) such as a spring, being separated away from the switch module 9 . Accordingly, whenever pressing the button 15 down, the switch module 9 is turned on. As a result, if the button 15 is clicked on, an electrical signal notifying that the button 15 is pressed down is transferred to the computer together with information related to a current position of the optical mouse 100 .
- the optical mouse 100 generates a signal corresponding to the current position of the optical mouse 100 by using external light such as natural light or a typical electric illumination. Accordingly, there is no need for a light emitting device as adopted in the conventional optical mouse. As a result, power consumption of the optical mouse 100 can be minimized.
- FIG. 2 is a schematic cross-sectional view showing an optical cursor control device according to a second embodiment of the present invention.
- an optical mouse 200 is movably placed on a worktable 210 .
- the worktable 210 is the same as the worktable 110 of the first embodiment.
- the worktable 210 has an upper surface 210 a with irregular surface morphology as well.
- the optical mouse 200 includes a case 51 , and a light guide 53 disposed at a sidewall of the case 51 .
- the case 51 has a lower panel with an opening 51 a , unlike the case 1 of the first embodiment.
- the light guide 53 has different form and function from those of the light guide 3 in the first embodiment.
- the light guide 53 has a light concentrating surface 53 a for receiving external light 69 of the case 51 , and an illuminating surface 53 b for illuminating the light passing through the light concentrating surface 53 a onto the upper surface 210 a of the worktable 210 .
- the light passing through the illuminating surface 53 b is illuminated onto the worktable 210 through the opening 51 a .
- the illuminating surface 53 b has an area smaller than that of the light concentrating surface 53 a . Accordingly, the light guide 53 increases an intensity of the external light 69 . That is, the light guide 53 acts as a light amplifying mean.
- the light introduced through the light guide 53 and the opening 51 a is reflected on the upper surface 210 a of the worktable 210 and is illuminated to an optical sensor 57 mounted inside the case 51 .
- the optical sensor 57 is mounted on a printed circuit board 55 disposed inside the case 51 , as in the first embodiment.
- the optical mouse 200 further includes a switch module 59 mounted on the printed circuit board 55 , a support 61 positioned above the switch module 59 , a hinge 63 connected to one side of the support 61 , a button 65 attached to the other side of the support 61 , and wiring 67 connected to the printed circuit board 55 .
- the optical mouse 200 may further include a light emitting device LD, which is installed in the case 51 .
- the light emitting device LD can be manually or automatically turned on when the external light 69 has a weak intensity.
- the lights from the light emitting device LD are irradiated onto the surface 210 a of the worktable 210 through the opening 51 a . Accordingly, even though the intensity of the external light 69 is very weak, it is possible to improve a sensing margin of the optical sensor 57 by turning on the light emitting device LD.
- the intensity of the light illuminated to the optical sensor 57 can be higher as compared to the first embodiment. Accordingly, a sense margin of the optical sensor 57 can be improved, resulting in an implementation of a high performance optical mouse.
- FIG. 3 a is a schematic perspective view showing an optical cursor control device according to a third embodiment of the present invention
- FIG. 3 b is a cross-sectional view of the optical cursor control device as shown in FIG. 3 a.
- the optical cursor control device includes a light concentrating pad 350 and an optical mouse 306 moved on the light concentrating pad 350 .
- the optical mouse 300 has a lower panel with an opening 301 a , as in the optical mouse 200 shown in the second embodiment.
- the optical mouse 300 does not adopt such light guides 5 and 53 as shown in the first and second embodiments. That is, the optical mouse 300 includes a case 301 , a printed circuit board 303 disposed in the case 301 , and an optical sensor 305 mounted on the printed circuit board 303 , as shown in FIG. 3 b .
- the optical sensor 305 is positioned above the opening 301 a to sense light emitted from the light concentrating pad 350 , as in the second embodiment.
- the printed circuit board 303 and the optical sensor 305 have the same functions as those in the first and second embodiments.
- the optical mouse 300 includes a switch module 307 mounted on the printed circuit board 303 , a support 309 disposed above the switch module 307 , a hinge 311 connected to one side of the support 309 , a button 313 attached to the other side of the support 309 , and wiring 315 connected to the printed circuit board 303 , as in the first and second embodiments.
- Each of the switch module 307 , support 309 , rotational axis 311 , button 313 and wiring 315 has the same function as that in the first and second embodiments.
- the light concentrating pad 350 includes a light concentrating plate 353 for reflecting light 317 such as natural light or an electrical illumination, an optical wave guide 352 for passing the light reflected from the light concentrating plate 353 , and a lower reflecting plate 351 attached to a bottom of the optical wave guide 352 .
- the lower reflecting plate 351 upwardly reflects the light transferred through the optical wave guide 352 .
- an upper transparent plate 357 is attached to a top of the optical wave guide 352
- side reflecting plates 355 are attached to sides of the optical wave guide 352 .
- the upper transparent plate 357 is attached to the top of the optical wave guide 352 .
- the light reflected by the light concentrating plate 353 is transferred through the optical wave guide 352 , and the light introduced into the optical wave guide 352 is reflected by the lower reflecting plate 351 and the side reflecting plates 355 so that it is emitted upwardly through the upper transparent plate 357 .
- the light transmitted through the upper transparent plate 357 is illuminated to the optical sensor 305 through the lower opening 301 a of the optical mouse 300 .
- the upper transparent plate 357 of the light concentrating pad 350 has regular patterns arranged in two-dimension.
- the optical sensor 305 recognizes the regular patterns arranged at respective positions of the light concentrating pad 350 to transfer them to the printed circuit board 303 .
- the printed circuit board 303 processes the patterns recognized by the optical sensor 305 to output an electric signal corresponding to a current position of the optical mouse 300 .
- the light concentrating plate 353 may be an inclined flat panel, as shown in FIGS. 3 a and 3 b . However, the light concentrating plate 353 may have a concave surface in order to increase an intensity of the light that is incident into the optical wave guide 352 .
- the optical cursor control device adopts the light concentrating pad for upwardly emitting the natural light or the electrical illumination to recognize the position of the optical mouse, in place of the light emitting device for emitting infrared rays or visual spectral rays that are harmful to the human body. Accordingly, it is possible to minimize power consumption of the optical mouse. Moreover, it is not required to adjust an incident angle of the light emitted from the light emitting device to be smaller than 160 as in the conventional art.
- FIG. 4 is a cross-sectional view for explaining a light concentrating pad of an optical cursor control device according to a fourth embodiment of the present invention.
- the optical cursor control device according to this embodiment includes a light concentrating pad and an optical mouse, as in the third embodiment.
- the optical mouse of this embodiment has the same structure as that of the optical mouse discussed in the third embodiment. Therefore, an explanation on the optical mouse will be omitted.
- a light concentrating pad 350 ′ of the optical cursor control device has a similar structure to that of the light concentrating pad 350 of the third embodiment.
- the light concentrating pad 350 ′ adopts a light source 359 in place of the light concentrating plate 353 of the third embodiment.
- the light source 359 may be a typical lamp other than a light emitting device for generating infrared rays or visual spectral rays. Accordingly, even in case that there is no an illumination system or natural light around the optical cursor control device, it is possible to sense the position of the optical mouse.
